Includes emergency stop and manual operation options.

• A. Runways
• B. Chairlift Capacity Plate
• C. Safety Features
• D. Audio-Visual Alert

Answer: (C)

Safety features are the system that protects riders and keeps the equipment controllable during faults or maintenance. An emergency stop provides an immediate halt of the drive when danger is detected or someone signals an urgent stop. Manual operation options let a technician or operator move or position the steps or belt during power loss or service work, ensuring safe access and control. Together, these elements define the safety features category, which is why this is the best fit. The other items don’t capture that combination: runways aren’t a standard term for escalator/moving-walk safety concepts, chairlift capacity plate relates to a different type of equipment, and while an audio-visual alert is a safety component, it doesn’t alone describe the emergency stop or manual operation capabilities.
